Problems solved by technology

[0003] The above seed spraying techniques, plant planting methods and blanket plant planting methods all show natural growth and natural succession. The community structure is difficult to control, and there is often a phenomenon of vegetation degradation or formation of a single dominant population in the later period. Most of the selected plants are upright. Herbaceous plants and shrubs, and due to problems such as too large or too small planting or seed density, the final plant community structure is unstable, showing a single shrub layer or herb layer phenomenon, the "empty foot" phenomenon is very obvious, and the water and soil conservation effect is relatively poor. Poor, measur

Embodiment 1

[0029] In this example, the planting combination of Donghong (pioneer shrub plant) + Wedelia (creeping plant rooting on nodes) is adopted on the slope.

[0030]Among them, Donghong is planted with cutting seedlings, the seedling height is 20-30cm, the young branches and shoots are cut off when planting, leaving only 2-3 branches, and the row spacing of planting plants is 30cm×30cm or 40cm×40cm. After 2-3 months of growth, Donghong will germinate 4-6 new branches, the growth length of a single branch will reach 60-100cm, the crown width will reach (40cm-60cm)×(40cm-80cm), and the effect of covering the slope is good , The coverage of shrubs per square meter reaches more than 90%. Wedelia is used as a direct covering plant on the slope surface. The plant is planted by direct cutting of stems, with 3-4 cuttings in each hole, and the spacing between plants and rows is (10cm-15cm)×(20cm-30cm). After planting, the plant has strong rooting ability and gradually Nodal roots and tille...

Embodiment 2

[0032] In this example, the combined planting method of Donghong (pioneer shrub plant) + copper money grass (creeping plant rooting on nodes) is adopted on the slope.

[0033] Among them, Donghong is planted with cutting seedlings, the seedling height is 20-30cm, the young branches and shoots are cut off when planting, leaving only 2-3 branches, and the row spacing of planting plants is 30cm×30cm or 40cm×40cm. After 2-3 months of growth, Donghong will germinate 4-6 new branches, the growth length of a single branch will reach 80-120cm, the crown width will reach (40cm-60cm)×(40cm-80cm), and the effect of covering the slope is good , The coverage of shrubs per square meter reaches more than 90%. As a direct covering plant on the slope surface, copper money grass is planted with ramets, 5-6 roots are planted in each hole, and the spacing between plants and rows is (15cm-20cm)×(15cm-20cm). After planting, the plant has strong rooting ability, Relying on the stems to root and gro...

Embodiment 3

[0035] In this example, the combined planting method of Lunmei (pioneer shrub plant) + banyan (creeping plant rooting on nodes) is adopted on the slope.

[0036] Wherein the wheel plum is planted with seedlings with a seedling height of 20-30cm and no branches. When planting, the terminal buds are cut off to promote the germination of side branches. The row spacing of planting plants is 20cm×20cm or 30cm×30cm. After 2-3 months of growth, the side buds of the wheel plum continue to grow, and 3-6 new branches germinate. The growth length of a single branch is about 15-30cm, and the crown width reaches (30cm-40cm)×(30cm-40cm), covering The slope effect is good, and the shrub coverage per square meter reaches more than 90%. As a direct covering plant on the surface of the slope, Ficus pagoda is planted directly with cutting seedlings, without branches, one plant is planted in each hole, and the spacing between plants and rows is (15cm-20cm)×(15cm-20cm). After planting, it grows qu...

Abstract

The invention provides a slope vegetation recovery method adopting combination of creeping plants and positive pioneer plants. The method comprises the steps that the creeping plants rooted on nodes are planted through artificial holes; planting pipes are inserted between ground cover layers of the creeping plants according to a set distance, through holes are formed in the pipe walls of the lower portions of the planting pipes, and pioneer shrub plants are planted in the planting pipes. By the adoption of the technical scheme, the shrubs are planted in a tubular mode, the creeping ground cover plants are planted in holes, the ground cover plants with high coverage degree can be rapidly formed, slope surface upper layer vegetation can be flexibly constructed according to the slope surface environment characteristics, and therefore a slope surface three-dimensional plant community structure is constructed. The scouring force of rainwater can be reduced in a multi-layer mode, the slope runoff is controlled, slope vegetation is promoted to develop towards a three-dimensional community structure, and stable slope vegetation is formed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a slope vegetation recovery method using a combination of creeping plants and positive pioneer plants. Background technique [0002] Slope vegetation restoration technology is currently mainly through seed spraying technology, plant planting methods and blanket plant planting methods to form slope vegetation in a way of natural growth and natural succession. Among them, the seed spraying technology is a method of spraying seeds on the surface of the slope soil through a spraying machine, and covering them with non-woven fabrics and other maintenance measures. Most of the plants are gramineous plants such as bermudagrass, tall fescue, and ryegrass. And leguminous plants such as edamame, pig's dung bean, and silver acacia. These plants have the characteristics of large seed quantity, sufficient provenance, high germination rate, and rapid vegetation rec...
